BUTTON-FASTENER.

SPECIFICATION forming part of Letter-s Patent NQ.31-3,199, dated June 8, 1886.

Application filed January 28, 1886. Serial No. 190,028. (No model.)

To @ZZ whom if may concern.-

Be it known that I, GEORGE W. PRENrIoE, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Button-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention,` such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying d rawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

This invention'relates to button-fasteners of that class known as prong-fasteners, comprising a plate or table and several prongs integral therewith, the said fasteners being adapted to carry a button and be secured to a shoe or other article by'means of the prongs, which are caused to penetrate and be clinched to the material to secure the button.

In buttonfasteners of the class mentioned the blanks are cut from sheet metal and bent to the desired form. The edges of said blanks being square with the dat surface, form sharp cutting-corners, and when attached to a shoe or other article are liable to chafe or abrade anything which may come in contact With said corners. 'Ihe square edges of the fastener also form shoulders against which the button-hook is liable to catch in buttoning the shoe or other article, all of which causes serious annoyance.

My invention has for its object to obviate these objections; andl it consists, essentially, in forming the blanks of such fasteners with chamfered or beveled edgeson the side which lies uppermost when the fastener is secured to material, forming the table and prongs of the fastener with a thick center and thin edge, all as will be hereinafter more fully described- Figure 1 is a plan view of a blank embodying my improvement. Fig. 2 is a cross-section of prong l enlarged. Fig. 3 is a perspective view of a button-fastener made from said blank. Fig. 4 represents the same with button as secured to fabric. f

To illustrate my improvement, I have shown in the drawings a button-fastener having three prongs, l and 2 2, the prongs 2 2 being on one side of the table 3, the prong l located at the opposite side, as shown in Fig. l. The prongs 1 and 2 2 are subsequently bent at right angles to the table 1, as shown inFig. 3, the prong l being bent to form the staple or eye 4, to engage the loop of a button when the fastener is secured to fabric, as in Fig. 4.

The blank A previous to being bent, as described, is manipulated by proper machinery, and the upper edges are chanifered or beveled entirely around, substantially as shown at 5, and illustrated by cross-section in Fig. 2 of prong I enlarged, thus forming the table and 'prongs with a thick center and thin edges,

which reduces the Weight of metal employed without materially affecting the strength of the fastener.

In place of cutting the blanks from sheet metal and chamfering the edges, the same result may be attained by casting or striking up the blanks in a manner Well-known.

A button-fastener thus formed is adapted for use on any kind of material, but especially so on thinstock-such as glove-kid and the like-as the table lies closely against the sur face of the material when secured thereto, and, having thin chamfered edges, forms a perfectly smooth surface with no abrupt shoulders into which. to catch the point of the button-hook, or sharp corners to cut or abrade articles of apparel in contact. The prongs readily penetrate the fabric in attachment, and when clinched on the under surface thereof also form a smooth surface with no projections to injure the fiesh of the wearer, thus overcoming the serious obj ections previously mentioned as incidental to the square-edged blank formed into a fastener. A strong and reliable fastener is thus produced at a nominal cost. f

I claim as new and desire to secure by Letters Patentl. The blank A, formed as described, comprising the table 3, provided with the prongs l and 2 2, the entire upper edge of said blank being chamfered or beveled, substantially as and for the purpose specified.

2. The button fastener herein described, formed from the blank A, consisting of the table 3, prongs l and. 2 2, and staple 4, said table, prongs, and staple being chamfered or IOO beveled entirelyT around the outer edges, arranged as shown, and adapted for use substmr tially as set forth.

3. A button-fastener comprising a table and 5 penetrating prongs integral therewith, said table and prongs being ehzuufered on their edges, substantially as and for the purpose specified.
